Version 1.6.6.0

New features:

• #263 New form "Projector" shows the 2D-view in fix scale, to be shown on the workpiece with an projector [Machine control - Projector].
• Additional forms (e.g. setup-form or text-creation) are not pinned to the front anymore, but can be brought to front via menu-button.
  To get the old mode (always in front) enable [Setup - Program appearance - 2D-View/Editor/Misc - Misc "Show other forms always in front"]
• Changed layout in main GUI: Select use of Router/Plotter/Laser to control spindle speed / PWM adjustment
  
• Scan height-map: new option to scan just one axis and extrude the other - Application on a rotation axis: scan along the rotation axis, extrude along the perimeter.

Improovements:

• If program was not installed, but just copied to "C:\program...", access rights are making trouble, when storing data.
  Fix: if the path "C:\program..." is recognized, a data-folder in User/documents will be created.
• SVG-import: take care of pen-width scaling
• Recognize USB/COM disconnection - save streaming status
• Form 'Convert Image' rearrangement of the controls, conversion to grayscale or black and white for better laser support
• Improoved exception handling

Bug fixes

#268 (connetion to marlin firmware)
#270 (tangential axis just turns 270° instead of 360° on G2/3 command)
#272 (wrong offset for tangential axis after GCode rotation, when not using 360° per turn)

New form "Projector":

Version 1.6.5.2

Fix #255

• implement bulge-import for DXFPolyline
• change variables for gcode generation from float to double (increases accuracy from 7 to 15 digits) to get rid of error 33 at large coordinates
• little improovement for telnet connection, but is still tricky
• add more exception handling
• changed installer-file - hope to get rid of access denied exceptions for the file current.csv

Version 1.6.5.1

Snap on grid, when moving selected figure and pressing shift-key:

• snap on grid only on x or y axis, when gripped on edge of selection bounds (see scetch below - yellow)
• snap on grid on x and y axis, when gripped on corners of selection bounds (see scetch below - orange)

If text is imported, left-click selects whole text, shift left-click selects single character

New setup-option "Command extension", to add new axis with travel-distance related value:

Version 1.6.5.0

New features:

• Improoved Object handling in 2D-view: added handles to selected object (figure or group) for moving, scaling, rotation. Add raster.
  To select a group (if enabled in [Setup - Graphics import - Path import - Grouping and tools] press "Ctrl" during selection of a figure.
  

• Adding Text to existing (formerly imported) gcode
  Tip: enable grouping in [Setup - Graphics import - Path import - Grouping and tools] to be able to select the whole text
  

• Ethernet connection (only tested with ESP32 )
  Frequency for status polling will be reduced automatically to 0.5 Hz.
  

• Reworked use-case dialog

Bug fixes:

• avoid error message on M6 command, if tool change is not enabled
• avoid error message on empty tool-change-script filename
• improoved exception handling

Version 1.6.4.0

Image - halftone conversion

• add background pattern

Add czech language

Some bug fixes:

• Z to S transform #245
• Improoved exception handling

Forgot to upload https://github.com/svenhb/GRBL-Plotter/blob/master/GRBL-Plotter/data/usecases/example_plotter_Z_axis.ini before release.
Also https://github.com/svenhb/GRBL-Plotter/blob/master/GRBL-Plotter/MachineControl/GCodeVisuAndTransform.cs was changed after release.

Version 1.6.3.5

New:

• Move logfiles to sub directory 'logfiles'
• Add logging for serial COM (may reduce performance) including log of send and echoed data (see screenshot below) - can be enabled in [Setup - Program behavior - Program start - Logging]
• Run time counter for spindle, flood and mist - can be resetted in [Setup - Program behavior - Program control - Accessory run times]
  

Bug fixes:

• Fix penup path: missing arrows and ids
• More improvements to avoid program exceptions

Version 1.6.3.4

More improvements to avoid program exceptions

Please provide feedback if any other exceptions arise

Version 1.6.3.3

More improvements to avoid program exceptions

Added File encodings for saving G-Code: [Setup - Program behavior - Program start - Miscellaneous]

Note: previous 'Unicode' = 'UTF-16', previous 'ASCII' = 'us-ascii'

Note info after saving:

Version 1.6.3.2

Improved exception handling, main problem: missing file-access rights after using setup-install-mode "Install for all users" (which needs admin rights).

Changed installation location for data-path, depending on setup-install-mode [Install for all users = admin] or [Install for me = non admin]

Data-path can be checked via "About" Menu-Item

• Old (non admin): C:\Users\user-name\AppData\Roaming\GRBL-Plotter\GRBL-Plotter

• Old (admin): C:\Program Files (x86)\GRBL-Plotter <- wrong, access protected

• New (non admin): C:\Users\user-name\Documents\GRBL-Plotter

• New (admin): C:\Users\public\Documents\GRBL-Plotter

Please provide feedback if any other exceptions arise

Other bug-fix:

When loading GCode with subroutine, Pen-down path was not visible, when using [Setup - Program appearance - 2D-view - Pen-down Color Mode]

Version 1.6.3.0

There is probably a rights problem if the program is installed with administrator rights.

Please select 'Install for me only' during installation.

New features

• option to show path-nodes (vertices) (=gcode coordinates) of graphics in 2D view (will be switched off on each program start to save recources) - [File - Setup - Program appearance - 2D-View]
• show status of D0-D3 of grbl-Mega-5X enable and set description: [File - Setup - Program behavior - Program start - Pin description]
• new extension "knock-in nut recess" [G-Code Creation - Extensions]
• support VoidMicro controller with just two grbl-axis: arkypita/LaserGRBL#1640 - not tested, feedback is welcome

Bugfix

• remove short moves

Show path-nodes - with and without "remove short moves":

Status of D0 - D3:

Extension "Knock-in nut recess":

Update: Version 1.6.3.1 with additional exception handling
